l. SPECIFICATION. TO ALL'WHOM IT MAY CONCERN:

Be it known that I, RIcHARn CHESTER, of Chicago, in -the county of Cook, and State of Illinois, have invented a newl and useful Improvement in Lanterns; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, andthe letters and gures'i marked thereon, which form part of this specication. l,

The nature of my invention consists in a novel arrangement for admitting air into the lantern, without dan ger of extinguishing the flame, i'n case of the 'wind blowin g into the apertures; andalso a novel arrangement in the top of the lantern, whereby the heated air readily passes out, while the wind caniot blow out the Haine. i To enable those skilled in the art ,to understand how to construct4 and use my inventionfI will proceed to describa the same withrparticularity, making reference, in so doing, to the aforesaid drawings, in whichi y Figure 1 represents a side elevation of my invention, the door' of the lantern beingopen.'

Figure 2 is a vertical central section of the same; and Figure 3 is a plan view of the horizontal plate G.

The same letters of reference in the diii'erent figures denote the same parts ofxny invention.

A represents the enclosure of the lantern, which consists of a rectangular frame,-containin g four panes of glass i l of the proper coniiguration, the same being narrower at the top, as shown. One `of said side's, marked A',

is hinged so as to form a door, as shown, being secured firmly when shut, by means of a pin or rod marked a,

passing throu'gh the sockets, b'b, upon the frame, and the tubular.catch,.a, upon the door.` This enclosure,A,

is securely guarded against breakage o r injury, by meansof the wire-guards, B, arranged as shown. C repre` i sents a platform or rest,- arranged a suitable distance above rthe bottom of the lantern, E, provided with guides,: c c, upon each side, upon and within'which theoil cup, D, mayslide and be withdrawn at pleasure,'by means of the. ring, d, or its equivalent for that purpose.v Through the centre Yof the bottom, E, there are suitable; apertures foradmitting air into the lantern,'labove which perforations isarranged the perforated enclosure marked F, which serves to disperse the wind and break its force before enteringthe enclosureef the lantern,1

which entrance is effected in the direction of the arrow s, as shown, the platform deilectingthe currentsof air i away from the flame until the force of the ,wind is expended, thusV preventing the extinguishing of `the flame l, thereby. In the top of the lantern is arranged the plate, Gr, closing the lower partof` the enclosureof 1 the i lantern from the top, except atthe four corners, asshown inrg. 3', through which openings the heated air rises i and passes out through the tubesH. r,The tubes H are closed at their outer ends byperforated caps, te break j the force of the wind, whiletheir inner ends extend within the toplof' the lantern far enough to give the wind the proper direction .to pass out through the opposite tube, and'not deilect down upon the' arne, which is further prevented bythe arrangement of the said horizontal plate, G. F

Having described' the nature, construction, and operation of my invention, I will now specify what I clailii` anddesire to secure by VLetters Patent l I. I claim the arrangement of the perforations in the centre of the bottom E, and the perforated enclosure l F, arranged beneath the platform C, for the lamp, as'and ,for the purposes described` 2. I claim thehorizontal tubes H, provided with'perforated cups, and extending Vvvithinh'the lantern top,`ae shown, in combination with the-diaphragm G, having openings at the corners, out of the range of said tubes, v

asrherein specified and set forth. i
